Mix completely with the spoon
Wait 15 minutes, and note any color change.

1 gallon of plain 6% bleach will add about 8 ppm of chlorine to your pool; start dosing with TWO gallons, each evening, till the green is gone.

Usually, you don't have metals in well water when you have high pH + high alkalinity + high calcium.

When buying bleach, check the strength of the bleach carefully. I haven't found any generic brand 6%. Walmart's is 4% and a lot of other stores don't tell you the strength and it is usually as low as 3%. You may find some Clorox in 6% strength.

If they still have it in stock, you can 12% liquid pool chlorine (bleach by another name), at CTC - the Aquaris brand is $4.69 for 5 litres, which is about 1.3 US gallons. As I learned here, if you don't use the 12% right away, keep it in a cool place as at 80 degrees+ it will lose strength very quickly... not a issue this weekend anyway.

The pucks sold at CTC, Walmart, or pool stores like Campbell or Mermaid all have stablizer in them. "stabilized chlorine" is not any different than bleach or other methods of delivering chlorine. It just means that they had included stabilizer (CYA) with the chlorine.

You can buy stabilizer (CYA) by itself, so you can bring up the stabilizer level and use regular bleach.

Stabilizer will break down over winter, so with the weather, and that we are pretty well at the end of the season, there likely isn't a big advantage in adding a lot now.

Ton of rain today, at least 2 inches. Had to drain the pool as the water level was above the skimmer.

Hi if I get the 4% one do I just put more in the pool or do I need the 6%?

Thx

[PoolDoc]

4% is fine; just add 1.5x as much.

Is 4% the more common strength in Canada?

Is 4% the more common strength in Canada?

3-4% is common for the supposedly cheaper store branded bleach. 5.25% is common for name brands like Javex or Clorox, but the cost is quite a bit more. Sometimes you can find 6% Clorox.

Walmart used to carry 6% in its generic brand, like in the US, but changed that to 4% last year while leaving the price the same. All the store brands that I have checked are 3% to 4%, which doesn't end up as much of a saving.

Just to edit - this is for my location and seems to hold for Ontario in the east. It may be different in Western Canada as there can be significant differences in what is available.

That's why I have steered Canuck posters to the 12% at Canadian Tire. 5 litres sells for $4.69 vs. $8.99 at the pool store.

[PoolDoc]

I gather that Canadian Tire is a multi-line distributor with many outlets in eastern Canada?

ya its like a Walmart, just a guys Walmart, lol
